Is it normal that i stopped dating a guy cause he has a small dick?

Honestly, it's disgusting how it's normalised that women can mock guys for having a small penis, just because they're women, and the people being mocked are men. Because apparently men don't have feelings, and so therefore it's ok to deride them for something they can't control, something that is inherently "wrong" with them physically (it's no different to mocking someone's physical disability). But if a man ever mocked a woman for having small boobs, then they'd always be viewed as despicable.

That being said, you're not one of those women, you didn't mock the guy, you were respectful to him. You didn't continue things with him because you just weren't attracted to him, the reason being because of his penis. There's nothing wrong with that, you can't control what you're attracted to. Some guys aren't attracted to women with small boobs, and there's nothing wrong with that either (so long as they're respectful to them). I don't think you should've ignored his calls though, I think you should've just made up some reason like that you weren't feeling great or something, just to spare his feelings.

Double-standards. If a guy rejected a girl because her vagina is too loose, he'd be labeled a sexist, and it'd be considered body-shaming. But shaming guys for their PP size? Totally fine.

I don't think I would stay with someone who has such a small dick too. I'm not into sizes but a micro penis is a no no. However I would not just ignore his calls.
I'm sure he knows why you are not taking his calls and maybe it's not the first time that this happens to him. That's sad though.
I had a friend who met a guy online and travelled to meet him to find out that he had a micropenis. She slept with him several times but it just could not work because she barely felt anything.
That's real sad.

Woman hate it when men judge their capabilities based on the size of certian things. Men hate it too.

The size of any of those things has nothing to do with how good a person, a provider, or even a lover they are. Many men know (or are willing to learn) how to sexually please a woman - independent of their penis size.

I think you need to look yourself in the mirror and ask if this is what kind of person you want to be. Focused solely on physical attributes... or do you wish to focus on how they think, their values, and if they are compatible for a long term relationship, would be a good provider and partner in life; or even marriage and having their children.

You can do better than how you reacted.

I also agree with Lusty-Argonian that you need to be honest with him and talk to him.

I suspect that if you give him a chance that he may surprise you with other aspects of himself.

It's OK to admit that you made an initial judgement that you now recognize was in error.

I wish you the best,

Ya l know they make hallow strap ons for a reason

Well everyone has their preferences, not much to do about it.
Just tell him you don't think it's going to work out between the two of you and move on.

I'm sure he knows he is small. Are you open to a poly relationship or multiple partners? Maybe he is as well. Could work out well if you're into it.
Have a bull as a play toy and if everything else is good and works with this guy, who knows where it could go not many guys are good with knowing their girl wants a little more but I bet he understands. Give him a bj while the bull is have his way elsewhere at least you won't be gagging. Give him a chance at least to see if he's open to another player. That is if you are.
